10 Claims.

This invention relates to nails, sometimes termed alpine nails, adapted to be fastened to the y*soles of shoes or boots used in mountain or glacial regions and designed for anti-skid purposes on any icy or similar slippery surfaces.

An object of the present invention is to provide an alpine nail for a boot or shoe which is formed from a single metal blank and is provided with integral means, such as prongs, for attaching the device to the sole of the boot or shoe.

A further `object of the rinvention is to provide a nail or .anti-skid cleat-like device attachable to the sole of a boot or shoe by means of iish hook prongs formed vintegrally from a single metal blank which in turn is provided with anti-skid means to prevent slipping on'icy or other similar surfaces.

Still another object of the invention is to provide an anti-skid alpine nail attachable to the sole of a boot or shoe and economically formed in improved manner from a single metal blank by vstamping and/or punchpress operations.

A further object of the'invention is to provide an improved alpine `or anti-skid nail which is generally V-shaped in -cross-section, having jagged or saw-tooth edges for anti-skid purposes and also having integral means by which the device may be attached directly to the bottom of a boot or shoe sole. y

A still further object of the invention is to provide a V-shaped nail of the foregoing character provided with attaching prongs adapted to be driven into the sole of the shoe and preferably formed so as to anchor themselves in the sole against ready withdrawal.

Another object of the invention is to provide an alpine nail of the foregoing character provided with hook-like prongs adapted to be driven into the shoe sole to anchor the device therein.

Other objects of this invention will appear in the following description and appended claims, reference being had to the accompanyingdrawing forming a part of this specification wherein like reference characters designate corresponding parts in the several views.

Fig. 1 is a view of a boot or shoe carrying antiskid nails embodying the present invention.

Fig. 2 is an enlarged section through the sole and nail.

Fig. 3 is a bottom plan view of the boot or shoe of Fig. 1.

Fig. 4 is a perspective View of the nail or antiskid device.

Fig. 5 is a View of a flat punched blank before certain bending operations.

tion is capable of other embodiments and of being practiced or carried out in various ways. Also it is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation.

In the drawing there is illustrated a present preferred form of an4 anti-skid nail or device, generally designated at A, constructed in accordance with the present invention. preferably formed from a single blank of relatively heavy gauge sheet steel, see Fig. 5,y and is designed for attachment to the bottom of the sole B of a mountain boot or shoe C.

The nail illustrated in accordance with the present embodiment of the invention is V-shape in vcross-section comprising sides I0 and II in tegrally formed from a single metal blank and extending at an acute angle with respect to each be'punched out or cut away .at I2 and I3 to provide projecting prongs I4, Ilar and Mb. Prel'erably two oi the prongs I4 and; Ila extendirom yone-half of the blank, with the cut-away portion I2 somewhat wider than the cut-away portion I3. The lower edge of the blank is blanked out to provide a jagged or saw-tooth edge I5. A portion of the metal between the prongs I4 and Illa is left to form a tongue I6 having a hole I'I for the reception of a fastening element. The outer edges of the prongs I4, I4a and Ilibare notched at I8 and the ends are wedge-shaped or pointed at it. The blank, illustrated in Fig. 5, may be bent along the dotted line 2i) into V-shape with the two prongs Ill and Illa extending from the side lli and the single prong Mb extending from the side I I. .In this same operation, or at any other 'operation in the formation of the device, the tongue i6 may be bent inwardly along the dotted line 2| so as toextend at right angles to the side it.

The nail, thus formed as shown in Figs. 4, 6 and 7, may be attached vto the Sole of the boot orshoe C in the manner illustrated in Figs. 2 and 3.v The prongs are driven into the sole. burying the hook-like ends in the leather. By virtue of the notches it the prongs in effect vfunction similarly to fishhooks and securely anchor themselves in the sole against ready removal. When The nail is the nail is driven fully into the sole, as shown in Fig. 2, the tongue I6 abuts or comes up against the bottom of the sole. To insure unquestionable anchoring of the nail to the sole against any danger of displacement or loosening during hard usage, a brad or other ordinary nail or fastening element 22 is driven through the hole I1 into the shoe sole and clinched over, if desired, to prevent Withdrawal.

An alpine nail constructed in the foregoing described manner has considerable advantages in usage, being strong and durable, and constructed to afford excellent gripping or anti-skid qualities on icy or slippery surfaces. In addition, it may be economically manufactured from a single metal blank and easily attached to the sole of the boot or shoe.

I claim: y

1. An anti-skid boot or shoe nail formed from a single metal blank comprising a generally V- shaped body having jagged lower edges, integral prongs adapted to be driven into the sole of the shoe and a projecting part lying between the sides of the body and overlying said sole.

2. An anti-skid boot or shoe nail formed from a single metal blank comprising a generally V- shaped body having jagged lower edges and integral prongs adapted to be driven into the sole of the shoe, and an attaching tongue struck from the metal of one side of the body and apertured to receive a fastening element adapted to be driven into the sole.

3. An anti-skid boot or shoe nail formed from a single metal blank comprising a generally V- shaped body having jagged lower edges and integral prongs adapted to be driven into the sole of the shoe, and an attaching tongue struck from the metal of one side of the body and apertured to receive a fastening element adapted to be driven into the sole, said tongue extending at substantially right angles to the body and within the space between the sides thereof.

4. An anti-skid boot or shoe nail comprising a body having angularly related sides formed from a single metal blank, the lower edges of said sides having teeth, the upper edges having projecting pointed prongs adapted to be driven into the shoe sole, and one of said sides having an inwardly projecting portion adapted to engage the sole.

5. An anti-skid boot or shoe nail comprising a body having angularly related sides formed from a single metal blank, the lower edges of said sides having teeth, the upper edges having projecting pointed prongs adapted to be driven into the shoe sole, and one of said sides having an inwardly projecting portion to engage the sole and apertured to receive a fastening element.

6. An anti-skid boot or shoe nail comprising a body having angularly related sides provided with projecting prongs adapted to be driven into the shoe sole, and an attaching tongue formed from the metal intermediate said prongs and positioned to overlie the shoe sole.
